Public Cloud Computing Helping Organizations to Enhance Their IT Infrastructure
Public Cloud is one based on the standard cloud computing Model in a way a service provider makes resources.
A public cloud is a Multi-tenant service which is based upon the standard module of cloud computing where a third party service provider provides resources like Cloud Storage, Virtual Machines (VMs) and Applications to end users over the internet.
End Users have no control or visibility over the placement of the infrastructure. Services are either free, very low cost or are on a pay per usage model, so a waste of resources is inevitable.
We can not select cache, hardware or storage performance (SAS/SATA) in the public cloud. Public cloud provider only decides the hardware part and the network for the user. Also, PCI, SOX or HIPAA compliance cannot be provided in the public cloud because it is a multi-tenant environment where the user’s server shares the network devices, storage and hardware with other multiple users in the cloud.
This is completely different from the private cloud and hybrid cloud as private cloud is used by organizations for their own use, and hybrid cloud is a combination of public cloud and private clouds.
The public cloud comprises of a Huge range of products and services, including infrastructure as a service (IaaS), software as a service (SaaS), and platform as a service (PaaS). As per Gartner, the worldwide public cloud services market is projected to grow 17.3 percent in 2019 to total $206.2 billion, up from $175.8 billion in 2018.
So why is public cloud gaining importance? Public clouds can be deployed faster and with more scalability and accessibility than on-premises infrastructure so as a result of which the public cloud providers are expanding business boundaries and growing faster. The top cloud computing vendors providing public cloud services include Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP ), Adobe, VMware, IBM Cloud, Kamatera, phoenixNAP, to name a few.
Public Cloud is important for whom
Developers and testers of application codes who fire up and tear down development servers regularly.
Those who require scalability, the capability of adding compute resources at peak times.
Those doing projects in collaboration with different teams.
Those running web servers where data security is not a major concern.
Those who have Software as a Service application from third party implementing proper security strategies.
Those who are using Platform as a Service for doing ad-hoc software development projects.
Public Cloud Market value
As per IDC the International data corporation, cloud services will show double-digit growth across the globe. USA showed 64% growth in revenue in 2015, will witness a drop of 4% and will account for 60% growth by 2019. Asia Pacific which excludes Japan and Latin America will account for public cloud’s highest growth rates in the next 5 years.
Model number 2 for Public IT Cloud Service
Experts predict the competition amongst existing cloud service providers to continue and is not likely to be intervened by any other cloud service provider in the near future at least. Because public cloud needs very heavy investment, as well as masses of tech talent to support the underlying infrastructure.
